scope:

This International Standard specifies the form and meaning of programs written in Ada. Its purpose is to promote the portability of Ada programs to a variety of data processing systems.

Extent

This International Standard specifies:

• The form of a program written in Ada,

• The effect of translating and executing such a program;

• The manner in which program units may be combined to form Ada programs;

• The languagedefined library units that a conforming implementation is required to supply;

• The permissible variations within the standard, and the manner in which they are to be documented;

• Those violations of the standard that a conforming implementation is required to detect, and the effect of attempting to translate or execute a program containing such violations;

• Those violations of the standard that a conforming implementation is not required to detect

This International Standard does not specify:

• The means whereby a program written in Ada is transformed into object code executable by a processor;

• The means whereby translation or execution of programs is invoked and the executing units are controlled;

• The size or speed of the object code, or the relative execution speed of different language constructs;

• The form or contents of any listings produced by implementations; in particular, the form or contents of error or warning messages;

• The effect of unspecified execution

• the size of a program or program unit that will exceed the capacity of a particular conforming implementation
